Pros
The work is actually good. PHFI has some great projects, headed by highly qualified public health professionals. Highly reputed collaborators and funding agencies. Salary is higher than industry standards. Work-life balance is good.
Cons
The management is slacking possibly due to the massive, unchecked growth of the organization in the last few years. There is prevalent culture of favoritism. Few managers and directors in senior positions hold the key to senior most management. This can be frustrating for mid-level employees. You have to either submit to it and imitate others (suck up to managers) or prepare to be completely side-lined. There is no formal method followed for promotions and performance-based salary hike. If the your supervisor likes you - great! Or else be happy with the average 12%. As its said - No good deed goes unnoticed. Doesn't apply to PHFI. Don't try to be honest and in love with your work and expect that it will be rewarded. Also, there is ridiculously competitive environment when it comes to scientific paper writing. Don't be surprised if you hear of senior supervisor's fighting over authorship.
